It happens more often than you think. I also agree with Alpha some that do go ROTC decide the military is just not for them
That being stated, any SA and even college is difficult to adjust to the first few months.
Several years back one of our friend's DS wanted to leave. He came home at Thanksgiving and was pretty much determined he was going to go civilian. He wanted to finish out the semester, go to a CC for spring and transfer to his back up school the following fall. His parents were understanding, and made a deal with him. They would give 1000% support if he stuck it out for the full year. They even paid for his admissions applications to reapply as a transfer.
He agreed to their terms, and his parting words were basically I WILL be at a civilian college next fall.
Long story short. He commissioned out of the AFA. His folks were smart enough to understand that the hardest year is freshman. He was going through an adjustment period like any college kid away from home, but just on steroids,
If you want to transfer you can do it, but look inside yourself and ask why? Is it the BS of eating your meals sitting at attention and reciting things, than in 6 months that crap will be a thing in the past. If it is you just realized that SAs are not LACs than maybe you should re-think about staying, because academically you will take a lot of STEM classes as a Military History major compared to someone at a civilian college.
If you are a football fan, than you might feel differently when you go to your 1st game and feel the camaraderie at an SA.
I am not pro or con either way, but I am someone that has had 3 kids go off to college, and each one of them as freshmen had that moment of doubt and questioned their decision. It usually occurred at the 6 week marker. The high of getting out of the nest, and starting a life met reality of their new life.
~ I am not comparing any SA to college, I am comparing the emotions that kids going away feel for the 1st time, and at 18 most kids don't realize that is part of the equation.
~~ As Alpha stated some drop out of ROTC after coming from an SA. Thus, it was not about the SA life IMPO, it was they were not or are not ready at that age to commit to the military.
Take the time to ask yourself which one of these categories you fall in before you take another step.
